NEVER immerse the connector in water without connecting
with the transceiver. If the connector becomes wet, be sure
to dry BEFORE connecting it to the transceiver.
NOTE: The microphone is located at the top of the
speaker-microphone, as shown in the diagram above. To
maximize the readability of your transmitted signal
(voice), hold the microphone approx. 5 to 10 cm from
your mouth, and speak in a normal voice level.

■ Attachment

Insert the speaker-microphone's connector on to the [MIC/SP]
connector and carefully screw it tight, as shown in the dia-
gram below. Be careful not to cross thread the connection.
Set the triangle
mark to the front
side.
CAUTION: Attach the speaker-microphone's
connector securely to prevent accidental
dropping, or water intrusion in the connector.
IMPORTANT: KEEP the transceiver's [MIC/SP] connec-
tor cap attached when the speaker-microphone is not in
use. Water will not get into the transceiver even if the
cover is not attached, however, the terminals (pins) will
become rusty, or the transceiver will function abnormally
if the connector has become wet.
